摘要

In order to fabricate tandem-structured polymer photovoltaic cells, thinner-film photocells with different soluble C{sub}60 derivatives as the acceptors are fabricated and characterized in detail. It is shown that the aggregation, derived from the compatibility and the dispersion, of the acceptors in the polymer matrix (the donor) determines the film forming properties, the optimized content of the acceptors, the best thickness of the blend film for devices, and the apparent power conversion efficiency of the corresponding photocells. In the photocells with MEH-PPV [poly(2-methoxyl-5-2'-ethylhexyoxyl-l,4-phenylene vinylene)] as the donor, the device with a film thickness of only 60 nm, HN-C{sub}60 as the acceptor exhibits the better power conversion efficiency of 1.6% than that of PCBM as the electron acceptor which is employed widely in the investigation of high-efficiency polymer photovoltaic cells. The series resistance and the shunt resistance of the different photocells are also extracted and analyzed as a result of the aggregation of polymer and C{sub}60 molecules in the active layer to explain the performance of the photocells based on the distribution of acceptors in the active blend films.
